SPINNING, DOUBLING, AND TWISTING MACHINE.

dated March 9, 1897.

Application tiled February Z4, 1890. Serial No. 341,483. (No model.)

To all whom, it may concern:

Be it known that I, FRANCIS SEYMOUR, of Paterson, Passaic county, State of New J ersey, have invented a new and useful Improvement in Spinning, Doubling, and Twisting Machines, of which the following is a full, true, and exact description, reference being had to the accompanying drawings.

This invention relates to an improvement in that class of machines in which the raw hard silkis spun, doubled, and twisted in one operation. The raw hard silk in these machines is delivered upon spools, and the object is to spin the same, to double two or more threads, and to twist these combined threads, which process is ordinarily carried out to-day by two or more machines.

By my invention I am enabled to arrange a compact device in which not only are these operations carried on in one machine, but the said machine can be readily duplicated around a single driving power, so as to en-v able a numberv of them to be arranged in a very compact space.

My invention will be readily understood from the accompanying drawings, in which- Figure l represents a front elevation of my device; Fig. 2, a lateral elevation, partly in section, of the same; Fig. 3, a plan view; Fig. 4, a plan view, partly in section; Fig. 5, a detail of the automatic friction driving mechanism; Fig. 6, a vertical section through the traverse motion of the receiving-spool; Fig. 7, a section through Fig. 6 on the line @c ai; Fig. S, a detail of the spool-supporting frame. Fig. 9 shows a modification of the machine arranged for tram or twist, and Fig. l0 a detail of the doubler-rods.

The parts of my machine are supported in a suitable frame, (not fully shown,) and the spinning devices may be duplicated to any convenient extent around the driving-wheel B, driven from the shaft A. The drivingwheel B drives the spools by friction instead of by belts, which is a great advantage, owing to the liability of the belts to break 'and thereby injure a considerable amount of material. The spinning-spools are driven from the friction-wheels C D, one arranged a little above the other, as plainly shown in Fig. 6, for a purpose to be hereinafter explained.

These spinning spools and the receivingspool are mounted together upon a frame Z,

which is supported in the socket G by pin G',

(see Fig. 8,) and is therefore capable of lateral revolution in the socket. The frame Z and the supported spools are capable, likewise, of rotation around the pivot H at right angles to the socket G, whereby the spinning apparatus is brought in contact with the drivingwheel B. It is normally held in contact with said driving-wheel by means of the spring N, to which is attached a cord or chain M, passing around a pulley 7, the other end of the cord M being attached to the pivoted frame Z, as, for instance, by the stud O. The spring is held in its strained position by a hook 8, which hooks upon the part V normally, but can be released therefrom when the stop mechanism operates, as hereinafter to be explained. This spring N serves to maintain a constant and suflicient. frictionpressure between the driving-wheel B and the wheels C D, which are preferably provided with a soft or friction surface, as plainly shown in Fig. 5. I

The wheels O D themselves drive two other wheels E F, the lower one, F, being of slightly less diameter than the upper one, E. Through these wheels E F the receiving-spool and its traverse are operated, as will be hereinafter explained. The wheels I) O rotate the spinning-spools on spindles 5 6, and these wheels and the spindles are supported in the pivoted frames J J, pivoted as at L, and drawn toward wheels E F, respectively, by springs K K, permanently attached to part of the frame Z. In this way a constant driving friction is maintained between the wheels O D and the wheels E F, and the wheels C D, being independently mounted and capable of vibration on their axis of support, a uniform and sufficient friction is readily obtained, thereby allowing for any Wear on the driving parts. The hard silk on the spoolsP P', mounted on spindles 5 6, is directly spun in the usual way around these spools. The threads then pass upward around the tension-wires 9 9, then separately over the guide-rod, then through the fallereyes IV, and, finally, are united around the tensionwire 10, after passing over a second guiderod arranged on the opposite side of the faller- IOO eyes. This is clearly shown in Figs. 1 and 2, which show tension-wires 9 and 10 and the faller-eyes W supported by thethreads passover three doubler-rods 20, 2l, and 22, passing over the guide-rods. If the threadbreaks, ing underthe first rod 20, over the second rod the faller-eyes drop, stopping the machine, as 21, thence through the faller-eye, and then will be hereinafter explained. From the tenover the final rod 22, and thence through the doubling-eye 9. Thence the doubled threads pass as before to the tubular flier X.

Vhat I claim as my invention, and desire to secure by Letters Patent, is`

1. The combination in aspinning, doubling and twisting machine, of two spinning-spool spindles and provided with friction-wheels a silk to be doubled and twisted. The silk threads pass from the spools 19 under and tubular ier, but is capable of a vertical motion or traverse. It is driven from the wheel F, provided with a screw or feather 1.1, en-

which all of said spindles are mounted, and a friction driving-gear directly engaging the said friction-wheels on the said spinningspool spindles, substantially as specified.

and twisting machine, of two spinning-spool gages. l/Vhen this latch 3 has completed its traverse through one screw thread, it is switched or passes into the other screw-thread, thereby occasioning a reverse vertical motion upon the receiving and twisting spool spindle o f the spindle 1. By varying the relative impinging against one of the other frictionwheels and being -driven thereby, substantially as specifica.

The various bearings of the moving parts pivotal connection substantially as shown, are clearly shown in 10P G and do not require enabling the frame to swing about an axis at detailed desciiption The stop-motion is eoniight angles to its nist-mentioned movement,

by the faller-eyes W,

as shown and described.

4. The combination of the driving-wheel B, the frame Z carrying the spindle for the receiving-spool R, the friction-Wheel F secured struck by the striking-cam S, rotating on the shaft A. The levers 16 being pivoted to the striking-cam S forces these hooks outward past the plates V, thereby allowing tension on the cured to the latter-named spindles substantially as specified.

5. The combination of a spinning-spool spindles, tached to such spindles, the friction-wheels to be springs N. rhe downward' hooks driving-wheel, two friction-wheels atceiving-spool spindle, a friction-wheel attached to this spindle, means for driving this friction-wheel, and guides for leading threads from the spinning-spools to the receivingspool, substantially as specied.

. 6. 'Illie combination of two spindles carrywheel B, the parts being so balanced as that the center of gravity is beyond the pivot H.

ny set of spindles is then separately released from the driving-wheel B without interfering with the operation of any other set.

In Figs. 9 and l0 the machine is shown as arranged for doubling and twisting threads without spinning. In this arrangement spools 19, horizontally arranged, contain the and twisting spool and also provided with a friction-wheel, a driving-wheel for rotating the friction-wheelsof the two first-mentioned 2. The combination in a spinning, doubling ICO IIO

spindles, springs for causing frictional contact between the two first-mentioned frictionwheels and said driving-wheel, and a spring lfor causing frictional contact between the drivin g-wheel and the friction-wheels secured to the spindles carrying the spinning-spools, substantially as specified.

7 The combination ofthe driving-wheel B, the spindles 5 and 6, the wheels D and C attached thereto and frictionally driven from said driving-wheel, the iiier X and the receiving-spool R, the wheels E and F of different diameters attached respectively thereto, and frietionally driven from said wheels C and D, substantially as specified.

8. The combination of a number of supports for spools, a spindle for a receiving-spool, a frame carrying said spool-supports and spindie and having a hinged connection with its support and also a pivotal connection permitting said frame to swing about either a horizontal or a vertical axis, means for uniting or bringing together a plurality of threads and leading them to a receiving-spool, a flier, a traversing mechanism for moving the iiier lengthwise of the spindle and carrying the receivingspool, and wheels for driving said a different diameter from that of the wheel F so that said spindle and flier may be relatively operated at different speeds, the friction-wheels D C impingingagainst the Wheels E F, and the wheel B for frictionally driving the wheels D C, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
